To all whom it may concern.-

Be it known that I, AARON L. DURN, a citizen of the United States,residing at Richland Center, in the county of Bucks and State ofPennsylvania, have invented a new and useful Horseshoe, of which thefollowing is a specification.

This invention relates to horse'shoes, and has for its object to providea simply-constructed and easilyapplied supplemental call; to be attachedand detached, as required, and without removing the shoe from the hoofor changing its structure.

With these and otherobjects in view, which will appear as the nature ofthe invention is better understood, the saine consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation, it being understood thatthe invention is not necessarily limited thereto, as various changes inthe shape, proportions, and gen eral assemblage of the parts may beresorted to without departing from the principle of the invention orsacrificing any of its advantages.

In the drawings, Figure 1 is a perspective view from beneath of ahorseshoe with the improvements applied. Fig. 2 is a longitudinalsection of the same. Fig. 3 is a trans verse section illustrating theconstruction and manner of applying the toe-calks, taken on line a a ofFig. 1 and as indicated by the arrow. Fig. 4 is a transverse sectionillustrating the construction and manner of applying the heel-calk. Fig.5 represents perspective views of the two members forming thetoe-calk-holding means.

The improved device may be applied to any size or form of horseshoe andmay be attached without interfering with the calks already upon theshoe.

The improved device comprises a plate 10, extending transversely beneaththe shoe 11 and. bearing against the rear side of the toecalk 12 andwith upturned ends 13 14 bearing against the outer edges of the shoe. 7

Within the plate 10 the toe-calks 15 16 17 are secured, as by threadedstuds 18 19 20, the body of the calks being pointed and preferablysquare or of other form than round to facilitate the attachment andremoval by a wrench, pincers, or other implement.

Disposed transversely of the upper surface of the plate 10 and curved toconform with and bear against the inner side of the toe portion of theshoe is a clamp-plate 21, through which the stud 19 of the central calk16 extends, and with the ends of the plate extended over the upper faceof the shoe, as at 22 23. By this means the plate 10 is firmly clampedto the shoe and rigidly supported thereon by one single binding-screw.

If two calks only are required, which will be sufficient for the smallersizes of shoes or those used upon lighter horses, the central calk willbe replaced by an ordinary clampbolt; but this would not be a departurefrom the principle of the invention, as would be obvious.

The heel-call: portion of the device ,consists of frames 24, embracingthe shoe at the heel and bearing against the usual hecl-calks 25 andprovided with a set-screw 26, bearing against the inner face of the shoeto hold the frame in position. The sharpened calks 27 are connected tothe frames 24 by threaded spurs 28, and a locking-plate 29 is interposedbetween the frame 24 and the adjacent body of the shoe, with a rib 30bearing above the same, the setscrew 26 passing through the lock-plate,and thus holding it in position. The frames 24 may thus be readilyattached and detached when required and both sets of calks and theholding devices attached to or detached from the shoes without removalfrom the hoofs, while the spurs forming the calks may be attached anddetached without detaching the plates 10 and 21 or the frames 24, aswill be obvious.

The device is simple in construction, effective in action, maybeinexpensively manufactured and applied to any form or size of horseshoe.

Having thus described the invention,wl1at is claimed is 1. In ahorseshoe, a plate bearing against the rear face of the toe-calk andcarrying supplemental calks, and having upturned ends bearing againstthe outer face of the shoe, and means for detachably clamping said plateto the shoe.

2. In a horseshoe, a plate bearing against the rear face of the toe-calkand carrying supplemental calks, and having upturned ends bearingagainst the outer face of the shoe, a clamp member bearing upon saidplate and with extended ends bearing upon the upper face of the shoe,and means for clamping said member to said plate.

I 3. In a horseshoe, a plate bearing against the rear face of thetoe-calk and carrying supplemental calks, and having upturned endsbearing against the outer face of the shoe, a clam member bearing uponsaid plate and Wit extended ends bearing upon the upper face of theshoe, and a bolt con- 10 neoting said plate and clamp member.

In testimony that I claim the foregoing as my own I have hereto afliXedmy signature in the presence of tWo Witnesses.
